Silver/White of 15300, 15400 and 15202 is different?

[Watchcentric]

Hi,

In a recent question I posed on the 15300 vs 15400 someone replied that the 15300 is fine for the black dial and blue, but the silver/white of the 15400 is more beautiful and dynamic than the more flat white 15300.

I'm intrigued by this. At first sight the silver/white indeed looks rather flat (a bit like the 'real' white on the ROO's), but on the other hand it would strike me as odd that AP decided to use a different silver/white on the 15400 than on the 15300. And what about the 15202 by the way (not the anniversary version of course but the previous one)?

So is there really a difference between these Silver/white dials on these RO ST top models???

Thanks!
